CUTTING AND FOLDING MACHINE.

Specification of Letters Patent.

Patented Dec. 29, 1908.

I To all whom it may concern:

Be it known that I, RALPH C. SEYMOUR, a citizen of the United States,and resident of Larchmont, in the county of W estchester and State ofNew York, have invented a new and useful Improvement in Cutting andFolding Machines, of which the following is a specification. I

The object of my present invention is to materially simplify the meansfor assembling, cutting and folding sheets fed from a web, which meanscomprises rotary cutters mounted within the folding cylinders, the partsbeing so arranged that the operationof the folding devices and therotary cutters will be properly timed with respect to the other.

This invention is particularly directed to the means for cutting the webto form a collected group of sheets and comprises two rotary cylindershaving coacting rotary cutters mounted within said cylinders, one ofsaid cutters being fitted to rotate independently of its cylinder andthe other of said cutters being fitted to rotate with its cylinder, thetwo cylinders being of unequal sizes.

A practical embodiment of my invention is represented in theaccompanying drawings, in which Figure 1 represents in side elevationthe portion of a cutting and folding machine to which my invention isdirected, this view showing the geared connections at one side of themachine, Fig. 2 is a detail horizontal section taken in the plane of thecutter and cylinder shafts, Fig. 3 is a detail vertical section taken inthe plane of the line AA of Fig. 2, looking in the direction of thearrows, Fig. 4 is a similar view taken in the plane of the line B-B ofFig. 2 looking in the direction of the arrows, Fig. 5 is a brokensection taken in the plane of the line C of Fig. 2, looking in thedirection of the arrow, and Fig. 6 is a fragmentary view showing themechanism for controlling the opening and closing of the grippers on thetransfer cyl inder.

The side frames of so much of a cutting and folding machine as will benecessary to give a clear understanding of my invention are denoted by 1and 2. These side frames are provided, respectively, with inwardlyextended cylindrical lugs 3, 3*, and 4, 4*, through which the rotarycutter shafts 5 and 6 extend in parallelism with each other, the

shaft 5 being eccentrically mounted in its lugs 3 and 4.

The cutter shaft 6 is provided with geared connections 7, 8, with thecutter shaft 5, the proportions of the gears being such that the cuttershaft 5-will be rotated twice to every one revolution of the cuttershaft 6. The cutter shaft 5 carries two cutter blades 9, 10, arrangeddiametrically apart and the cutter shaft 6 is provided with a reel 16having two cutter blades 11, 12, arranged ninety degrees apart so thatduring two revolutions of the cutter shaft 5, the blades 12, 10, and theblades 11, 9, will coact once.

The folding cylinder within which the rotary cutter 5, 9, 10, iseccentrically mounted, is denoted by 13 and it has its hubs 14, 15,mounted to rotate on the cylindrical lugs 3 and 4. The folding cylinderwithin which the rotary cutter 6, 16, 11, 12, is mounted is denoted by50 and has its hubs 51, 52, mounted to rotate on the cylindrical lugs3*, 4*. These two folding cylinders are in parallelism with each otherbut out of parallelism with the rotary cutters.

The periphery of the folding cylinder 50 is one-third reater than theperiphery of the folding cylinder 13 and the two cylinders are driven atthe same surface speed so that the cylinder 50 rotates one revolution toone and one-third revolutions of the folding cylinder 13. The gearedconnection be tween these two cylinders 50, 13, is denoted by gears 17,18, mounted respectively on the hubs 51, 14 of the said cylinders. Thefolding cylinder 13 is provided with three slots 19, 20, 21, arranged atequal distances a art in its sides through which slots the b ades 9 and10 of the eccentrically mounted rotary cutter 5, 9, 10, are caused toextend to coact with. the blades of the rotary cutter 6, 16, 11, 12, atpredetermined times. The folding cylinder 50 is provided with a floatingfolding blade 22 and the folding cylinder 13 is provided with threefloating folding grippers 23, 24, 25, arranged to coact at predeterminedtimes with the floating folding blade 22 of the folding cylinder 50.These folding devices are of the well known floating type, the boX cam26 for controlling the floating of the grippers as they are broughtsuccessively into position opposite the folding blade being mounted torotate on the stud 4 of the frame and driven at the same speed as thesaid blade through the the reel 16.

geared connection 27, 28, the gear 27 being on the cam 26 and'the gear28 on the hub 52 of the folding cylinder 50, the groove 29 in said cambeing fitted to receive the operating stud rollers 30, 31, 32, of thethree folding grippers.

The box cam 33 which is provided with the groove 34 for receiving thestud roller 35 of the floating folding blade 22, is stationary. Byrotating the box cam 26 one revolution for every revolution of thefloating folding blade, the folding blade is brouglit into coaction withsuccessive sets of folding grip pers every one and one-third revolutionof the folding cylinder 13.

Three sheet carriers 36, 37, 38, which may be of the well knowndisappearing pin type are mounted in the rotary folding cylinder 13intermediate the three floating folding grippers, the operating arms 39*of which sheet carriers are arranged to be engaged successively by a cam39 carried by the box cam 26 for the purpose of withdrawing the carriersfrom their engagement with the sheets at the time the sheets are beingfolded on the cylinder 13.

A stationary cam 40 is provided in position to engage the rollers 41,42, 43, of the folding grippers 23, 24, 25, successively, every one andone-third revolution of the cylinder 13 for opening the sets of grippersto permit the folded sheets to be engaged by the set of grippers 44 onthe transfer cylinder 45.

Two stationary cams 46, 47, are rovided in position to engage the truckrol er 48 of the set of grippers 44 for opening the grip pers to receivethe folded sheets from the cylinder 13 and for opening the grippers todeliver the folded sheets onto a sheet carrier 49 of any desired form.

The folding cylinder 50 is driven from and at the same speed as thecutter 6, 16, 11, 12, as follows. The cylinder 50 is provided with across bar 50* extending between its ends, upon which cross bar I providean inwardly projecting ball 50** which is located in a socket 16** in anenlarged ortion 16* of This ball and soc 6t connection is in thehorizontal plane of the intersection of the axes of the cylinder andcutter so as to permit the free rotary movement of the cylinder andcutter even though their axes are out of parallelism.

The present arrangement of the several parts of the cutting and foldingmachine is such that after the preliminary series of operations areperformed for wrapping the web around the cylinder 13, a group of foursu erposed sheets are cut from the web and fol ded together by thecoaction of the cutting blades 12, 10, 11, 9, of the rotary cutters andthe coaction of the folding blade 22 with one of the sets of foldinggrippers 23, 24, 25; which folded group of sheets is transferred to thetransfer cylinder 45 and from there delivered on to the carrier 49. Therelative speeds of the several parts are such that the cutters and thefolding devices are caused to coact every one and one-third revolutionof the cylinder 13, the folding cylinder 50 being caused to rotate onerevolution to every one and one-third revolution of the cylinder 13 andthe cylinder 13 being caused to rotate one revolution for every one andone-half revolutions of the rotary cutter mounted eccentrically therein.It will thus be seen that the rotary cutter within the rotate within thefolding cylinder 50.

The parts shown and described but not claimed herein form thesubject-matter of 1907, entitled Cutting and folding machines, itsserial number being 397,623.

It is evident that various changes might be resorted to in theconstruction, form and arrangement of the several parts withoutinvention; hence I do not wish to limit smyself strictly to thestructure herein shown and described, but

l/V hat I claim is:
